Find Amplitude, Period, and Phase Shift y=sin(3x)
Problem
Solution
Identify the standard form of the trigonometric function
y=A*sin(B*(x−C))+D whereA is the amplitude,B affects the period,C is the phase shift, andD is the vertical shift.Determine the value of
A by looking at the coefficient of the sine function. Here,A=1 Calculate the amplitude using the absolute value of
A
Determine the value of
B by looking at the coefficient ofx Here,B=3 Calculate the period using the formula
(2*π)/|B|
Determine the phase shift
C Since there is no horizontal translation added or subtracted fromx inside the function,C=0
